Nemesis-class Heavy Battlecruisers (sometimes known as a Deep
Space Carrier or BC-314) are fictional spacecraft based on the science fiction
television shows, Stargate SG-1 and Stargate
Atlantis. Also referred to as a Deep Space Carrier and a 314, the
Nemesis class is the third generation of Earth battlecruisers and is designed to combat enemy ships, such as the Goa'uld,
Ori and Wraith class motherships. It succeeds the Prometheus and Daedalus as
the main vessel operated by the United States Air Force and its allies on
the two series.

There is currently only one confirmed active spacecraft in the
Nemesis
class series: the SG-SOCOM-operated Nemesis.

ALIEN TECHNOLOGY

The Nemesis class is fitted with much of the same advanced alien
technology as the Daedalus
class battlecruiser,
only all integrated into the original design before construction, as
opposed to being "tacked on after the fact" as was the case with
the Prometheus and Odyssey, as Lt. Col. Samantha Carter put it.

ASGARD

The Nemsis class contains a great deal
of Asgard technology, notably its
intergalactic hyperdrive, shields and beaming technology. The Nemesis
is also equipped with energy weapons, an Asgard computer core, and other
technologies, which Samantha Carter describes as "truly amazing".
The addition of the Asgard weapon systems were made possible when the Asgard
upgraded the Odyssey
before their race commits suicide due to a genetic disorder.

GOA'ULD / ANCIENT

The Nemsis class ships also have the same
ring transporters as Goa'uld vessels, which are known ultimately to be an
Ancient creation. These rings are compatible with rings onboard
Ori motherships as well as traditional
Goa'uld emplacements. When temporarily
genetically enhanced by Lantian technology, Rodney McKay wrote a formula on
how to enhance the shields on the Daedalus, it is unknown if it was
ever used.

The Nemesis class carries numerous Mark III and
Mark VIII tactical nuclear warheads and a number of railguns. Generally
speaking, the primary armament used by the Nemsis-class vessels is
the missile complement which is fired using vertical launching systems, with
all missile emplacements appearing at the bow and ventral hull emplacements,
like the Odyssey. Unlike
conventional vertical launch systems, it is possible to access the loaded
missiles from inside the ship, to swap their warheads, or entire missiles.
In Stargate Atlantis season three's "No Man's Land", Colonel Caldwell orders
the safety protocols to be disabled so that it is possible for them to fire
all their Mk. III nuclear missiles the moment they exit hyperspace to
increase the chance of a missile achieving a direct hit and not being
intercepted by the Wraith Darts.

In addition to a thick armor hull that is capable of withstanding brief but
intense fire from a Wraith Hive-Ship, the Nemesis class vessels are
fitted with advanced Asgard shielding that can defend the ship from incoming
hostile fire.

DESIGN

Similar in physical design as the
Daedalus class battlecruiser, as seen on Stargate Atlantis, the
Nemesis is slightly larger and has the same physical differences
from the Prometheus. It is sleeker and lacks the large aft tower.
Like the Daedalus class battlecruiser, the The
Nemesis-class also has four additional engine
emplacements on each side, making the rearmost part of the ship wider than
that of the Prometheus. There is a large square structure on the
ship's bow the purpose of which is unknown. F-302 bays are located on both
sides of the ship, below and out from the main hull along the rear.

There were huge advantages in space-savings with the increased usage of
alien technologies, thus the Nemesis class battlecruiser is able to
carry more fighters, cargo and troops than its slightly smaller Daedalus
class predessors.
The Nemeis' shields are also capable of standing up to multiple
Wraith Hive-Ships or Goa'uld motherships in combat.

HANGER BAY

The Nemesis class has two hangar bays on either side, and is capable of
carrying up to 32 F-302s,
as well as, 5 reverse engineered Puddle Jumpers with cloaking technology. The hangars come with doors and shields to prevent
decompression and expulsion into space.

The Nemesis (a 314) is the first starship to be produced of the
Nemesis
class of heavy battlecruisers. Based on known data of the Daedalus class
battlecruiser, it is believed that the ship took about one year to construct.

History

The Nemesis class battlecruiser was the
brainchild of Area 51's "Athena Project". Staying true to Greek
mythos, the "Athena Project" was named after Athena, Ancient
Greek Goddess of wisdom, crafts and strategic battle. With the technological
discoveries found at the Ancient Outpost on Antarctica and Atlantis,
combined with the Asgard technologies, the engineers at Area 51 redoubled
their efforts to build a battlecruiser that would surpass the Prometheus
and Daedalus class battlecruisers in every way. Blending all
available technologies in an effort to build a unique ship capable of taking
the fight to not only their old adversaries, the Goa'uld, but more
importantly, the newer threats; the Asurans, Ori and Wraith. With the defeat
of the fleet by the Ori at the SuperGate, the "Athena Project" was given full funding and the Nemesis class battlecruiser was finally
born. The Nemesis was launched from Earth less then 6 months
after the Ori invasion of the Milky Way Galaxy. Powered with at least one
ZPM, the ship's Asgard hyperdrive enables the Nemesis to reach the
Pegasus Galaxy and Atlantis in only four days . However, without the Ancient power
source, it takes Nemesis approximately 3 weeks to travel between
Earth and Atlantis.

In addition to serving as an effective transport, the
Nemesis has
experienced marked success in its function as a warship. With the main threat
in the Pegasus Galaxy
being the Wraith, the Nemesis is usually pitted against Wraith
Hive-Ships, which severely outclass the smaller ship in size, firepower,
and the capability of carrying fighter craft. The overall size of the vessels
make them difficult to destroy with anything less than nuclear weapons, which
are carried in only limited numbers and are easily destroyed prior to
detonation against a Hive-Ships hull. However, the advanced Asgard shielding
aboard the Nemesis has allowed her to stay in a battle long after a
Hive-Ship would have succumbed, and she has held her own in battle against the
Wraith (sometimes against more than one Hive-Ship) and has scored numerous
kills against the larger vessels. With the recent emergence of the Ori battlecruisers
in the Milky Way Galaxy, the various Ancient, Asgard, and Goa'uld
technologies will take this ship's name sake to heart. Meant to be the tip
of the spear, the Nemesis was assigned to SG-SOCOM.

The ship is named after Nemesis, Ancient Greek
goddess of Retribution. She is commanded by USAF TBD.
